SHAF holds bi-annual Work Days to restore and improve the historic landscape of the Antietam Battlefield and its environs. We do these in cooperation with the National Park Service and target areas where understanding the movements and combat as affected by terrain and vegetation are enhanced by our work. On March 1, 2025, Save Historic Antietam Foundation supported by Rho Kappa and a handful of Antietam Battlefield Guides assisted the National Park Service in clearing invasive brush honeysuckle from the East Woods near the intersection of Cornfield Avenue and the Smoketown Road. This work helps open up the woods and makes the terrain more visible.
